PORTABLE SHELVING.

SPECIFICATION forming part of Letters Patent No. 325,696, dated September 8, 1885.

(No model.)

To on whom it may concern.-

Be it known that I, CrmnLns H. Pos'r, residing at Guilford, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Portable Shelving; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming 1 art of this specification.

Theinvention relates to portable shelving for stores, book-cases, book-racks, desks, and all similar purposes.

Heretofore portable shelving has been connected by means of screws, by hooks and sockets of metal, and other appliances. The first is objectionable for the reason that it requires the aid of a tool to put them together or take them apart. The second method requires the hooks and sockets to be permanently secured to the shelving by means of screws or rivets, and are consequently difficult to pack and liable to be broken. The other appliances are equally objectionable.

The object of my invention is to provide fastenings for the shelves and sides or uprights by which they may be put together or tiken apartwithout the aid of tools, and without either metallic strips with openings, sockets, hooks, or other metallic appliances, being permanently attached by means of screws or rivets to either the shelf or side, so that when taken apart the woodwork and fastenings may be packed separately.

The invention consists in attaching metal lic castings by means of knobs engaging in undercut recesses formed in the shelves and sides in such a manner that the shelves are securely fastened to the sides thereby, as I will proceed to describe.

In the accompanying drawings, in which cess, and Fig. 5 a cross -section of Fig.4. through the line a a.

A represents the shelf; 13, the side; C, the

casting 7;, the knob, ands the undercut recess. There is nothing peculiar or novel in the formation of the shelf or the side, except there are I elongated undercut recesses formed therein. The undercut recesses have an enlargement at one end, as seen in Fig. 4, for the insertion of the knob it, which enlargement is at the top of the recess in the side, and at that end of the recess in the shelf which is farthest from the end of the shelf. The casting G is preferably right-angled, with knobs 7c is upon its top and end. as seen in Figs. 2 and 3. The top and end may be similar, so as to interchange.

The operation of the device is as follows: When one of the knobs is inserted into the undercut recess and drawn to the bottom, the edge of the casting will be flush with the end of the shelf, as seen at the left hand of the top shelf in Fig. 1. Now insert the other knob into the undercut recess in the side and push it to the bottom, and the shelf and side will be securely fastened and theundercut reccsses covered up. These castings may be made ofiron or other suitable metal, and of any convenient size and shape.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In combination with a shelf and its adjoining siding, both having the openings 8 leading into undercut recesses, one or more angular supporting brackets, 0, provided with knobs It is, adapted to enter openings 8, and when so entered to slip into and interlook with said recesses, substantially as herein described, and for the purpose specified.

2. In combination with a shelf and its adjoining siding, both having the openings 8 leading into undercut recesses, one or more angular supporting -brackets, C, provided with knobs k k, adapted to enter openings 3, and when so entered to slip into andinterlock with said recesses, said brackets being so extended at their free ends that they serve to cover the openings .9 when the several parts are properly assembled, substantially as described.
